You Are Not My Friend, But I Miss You by Daniel Kirk

You are not my friend.
Not anymore!

Monkey and his best friend, Dog, play games, enjoy sleepovers, and have the best of times together. That is, until Dog grabs Monkey's red ball and runs away.
Monkey decides that Dog is no longer his friend. He doesn't need a friend. He will be his OWN best friend. And that is a lot more fun. Or is it?
   Daniel Kirk, author of the bestselling Library Mouse series, has written a lively and humorous story about friendship with the gentle message that sharing requires both give-and-take.
